【摘要】：目的评估云南省沧源县地震后疟疾传播风险和流行潜势。方法根据2005-2015年4月中国疾病预防控制中心传染病报告信息管理系统(网报系统)的疟疾疫情数据和各省疾病预防控制中心使用"疟疾防治工作调查表"上报的疟疾疫情数据(年报系统),采用描述流行病学方法对云南省沧源县近10年来疟疾疫情和震后流行因素进行分析。结果网报系统数据显示,2005-2015年4月云南省沧源县共报告疟疾病例799例,间日疟652例,恶性疟127例,未分型20例。其中,2006年报告病例数最多(326例),地震后班老乡报告1例本地恶性疟病例。疟疾病例主要分布在芒卡镇(320例,40.1%)、班老乡(191例,23.9%)、班洪乡(98例,12.3%)和勐懂镇(92例,11.5%)等4个乡(镇)。年报系统数据显示,沧源县2005-2015年4月共报告本地病例519例,占总病例的58.4%;输入性病例370例,占41.6%。除2006年本地病例报告所占比例低于15%,其余年份本地病例均高于65%以上。风险评估数据显示,沧源县西部乡镇疟疾传播风险指数较高,其中芒卡镇和勐角傣族彝族拉祜族乡的疟疾传播风险指数最高。结论云南省沧源县由于地震后自然、社会、生物等因素发生重大变化以及仍然存在传疟媒介,该地存在疟疾传播风险。
[Abstract]:Objective to evaluate the risk and epidemic potential of malaria transmission after earthquake in Cangyuan County, Yunnan Province. Methods according to the data of malaria epidemic situation reported by the Center for Disease Control and Prevention of China from 2005 to April 2015 and the data of malaria epidemic situation reported by the provincial centers for disease prevention and control using the Malaria Prevention and Control questionnaire (annual report system), the epidemic situation of malaria and the epidemic factors after earthquake in Cangyuan County, Yunnan Province in the past 10 years were analyzed by descriptive epidemiological method. Results from 2005 to April 2015, 799 cases of malaria, 652 cases of vivax malaria, 127 cases of falciparum malaria and 20 cases of unclassified malaria were reported in Cangyuan County, Yunnan Province. Among them, the number of reported cases was the highest in 2006 (326 cases), and 1 case of falciparum malaria was reported in Ben villagers after the earthquake. Malaria cases were mainly distributed in Mengka Town (320 cases, 40.1%), Banao Township (191 cases, 23.9%), Banhong Township (98 cases, 12.3%) and Mengzhi Town (92 cases, 11.5%). According to the data of annual report system, 519 local cases (58.4%) and 370 imported cases (41.6%) were reported in Cangyuan County from 2005 to April 2015. With the exception of less than 15% of local cases reported in 2006, more than 65% of local cases were reported in other years. The risk assessment data showed that the risk index of malaria transmission in the western villages and towns of Cangyuan County was higher, and the risk index of malaria transmission in Mengka Town and Mengjiao Dai Yi Lahu Township was the highest. Conclusion due to the great changes in natural, social and biological factors after the earthquake in Cangyuan County, Yunnan Province, there is still a vector of malaria transmission, and there is a risk of malaria transmission in Cangyuan County, Yunnan Province.
